Red Sea Algae Control Multi Test Kit employs a comparator that eliminates fumbling or awkward handling of test vials as well as difficult to match color charts or color chips. Ease-of-use rewards new and experienced reef hobbyists with fast and accurate results. Routine and precise measurement of aquarium nitrate and phosphate levels is essential for monitoring unwanted algae growth in coral reef aquariums. High levels of nitrate and phosphate can not only fuel unwanted algae growth but can also affect coral growth and coloration.

Included quick guide walks you through the testing process with simple, easy-to-understand illustrations. Routine testing with Red Sea Algae Control Multi Test Kit is crucial to the health and success of any coral reef aquarium housing SPS, LPS and Soft Corals, especially those on a nitrate or phosphate reduction program.

Directions for Nitrate Pro Test Kit

Using the syringe provided, place exactly 16 ml of the water to be tested into both of the glass vials.

Insert one of the vials (control vial) into the outer hole of the Comparator.

Vigorously shake the bottle of Nitrate Pro Reagent A for 30 seconds and add 8 drops to the second vial (reaction vial). Close the vial with the cap and shake for 15 seconds.

Add 5 drops of Nitrate Pro Reagent B. Close the vial with the cap and shake for 15 seconds.

Add 5 drops of Nitrate Pro Reagent C. Close the vial with the cap and mix gently for 15 seconds.

Remove the cap from the reaction vial and insert the vial into the center hole of the Comparator.

Wait 9 minutes for the color in the reaction vial to stabilize at the end point.

When the end point of the test reaction has been reached, look into both vials from above and rotate the color disc until the closest color match possible is achieved between the vials. Note: Turbidity or severe coloration of the water sample (high organic load) may distort the colors.

The nitrate level corresponding to the color selected is printed on the color disc as indicated by the pointer on the side of the comparator body. If necessary, estimate an intermediate value.

The color in the reaction vial will remain stable for 5 minutes. Do not relate to the color in the reaction vial after this time.

High Range: For levels of nitrate above 4ppm, dilute 1ml of the water to be tested with 15ml of RO water.

Directions for Phosphate Pro Test Kit

Using the syringe provided, place exactly 17 ml of the water to be tested into both of the glass vials.

Insert one of the vials (control vial) into the outer hole of the Comparator.

Add 10 drops of Phosphate Pro Reagent A to the other vial (reaction vial), close the vial with the cap and shake for a few seconds.

Add 2 drops of Phosphate Pro Reagent B, close the vial with the cap and shake for a few seconds.

Remove the cap from the reaction vial and insert the vial into the center hole of the Comparator.

Wait 6 minutes for the color in the reaction vial to stabilize.

When the end point of the test reaction has been reached, look into both vials from above and rotate the color disc until the closest color match possible is achieved between the vials. Note: Turbidity or severe coloration of the water sample may distort the colors.

The phosphate level corresponding to the color selected is printed on the color disc as indicated by the pointer on the side of the comparator body. If necessary, estimate an intermediate value.

The color in the reaction vial will remain stable for 5 minutes. Do not relate to the color in the reaction vial after this time.

High Range: For levels of phosphate above 1 ppm, dilute 2ml of the water to be tested with 15ml of RO water.

General Information

Important notes for using the Colorimetric Comparator Test Kits

Before testing, clean the glass vials and the large syringe by rinsing with the water to be tested.

After testing, rinse all syringes and vials with RO or distilled water before storing. If vials are left unwashed, a residue can form that will affect the results of future tests. Use a slightly acidic solution such as vinegar to remove the residue.

Close all reagents tightly immediately after use.

The test reagents are stable up to the date stated on the pack when stored closed between 15 - 25°C (59 - 77°F).

Store the reagents and color card in the plastic box to prevent damage from prolonged exposure to light.

Assembling the Colorimetric Comparator

Press the catch in the recess of the base outwards and raise the body of the Comparator from the base.

Place the color disc onto the base so that the white surface on the base is in the center of the disc.

Replace the body of the Comparator by hinging it to the base at the back and pushing the catch through the center of the disc. The color disc should rotate freely in the Comparator. NOTE: In order to maintain the high accuracy of Red Sea's colorimetric comparator Pro Tests, they are supplied with special optically clear glass vials that have a slightly smaller diameter than the regular glass vials supplied with all other kits. To prevent mistakes, the regular glass vials do not fit in the Comparator.
